TYPE-WRl'l'lNG MACHINE.

SPECIFICATION forming part of Letters Patent No. 747 ,259, datedDecember 15, 1903- Application led April 8, 1901. Serial. No. 54,894.(llo model.)

To @ZZ wiz/m, t may concern:

Be it known that I, ANDREW W. STEIGER, a citizenof the United States,and a resident of Bridgeport, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inType-Writing Machines, of which the following is a specification.

This application relates to the type actions to of writing-machines.

Generally the key-lever system is of greater width than the type-barsystem, laterally-inclined connecting-rods being used in some casesbetween the side key-levers and typebars, and the levers of othermachines being crowded together so as to bring them within a space asnearly equal as possible to the width of the type-bar system.

The main object of my invention is to avoid zo the necessity of undulycrowding the key-levers together or of using inclined connections at thesides of the machine, which have a more or less cramping effect'upon thekeylevers and produce uneven wear on the typebar pivots.

To these and other ends my invention consists in certain combinations ofdevices, features of construction, and arrangements of parts, all aswill be hereinafter fully set forth,

3o and particularly pointed out in the concluding claims.

In the accompanying drawings, in which my improvements are shown inconnection with the type system of a Yost writing-machine, Figure 1 is asectional elevation taken longitudinally of the machine. Fig. 2 is asection taken transversely of the machine and about centrally of thetype system. Figsl 3 and 4t are side and front elevations of a key- 4olever hanger or post. Fig. 5 is a sectional detail of ajoint. Fig. 6isafragmentary sectional plan of a portion of the key-levers and theirtype-bar connections. Fig. 7 is a diagrammatic plan of the key-lever andtypebar system.4 Fig. 8 is a plan of a blank used in forming aconnecting-rod. Fig. 9 is an edge view of a complete connecting-rod.

In the several views portions of the machine are omitted or broken awayto more 5o clearly disclose the invention, and similar parts aredesignated by similar numerals of reference.

Each of the type-bars comprises arms 1 and 2 and a link 3, pivoted uponthe free ends of said arms and having at its free end a type 4, whichnormally contacts with an ink-pad- 5, whence it may be swung upon saidarms to make an impression uponthe under side of the platen 6, asillustrated at Fig. 2. The arms 1 are pivotally supported at their innerdisk-like ends upon a hollow annulus 7,whicl1 is fixed upon a bracket 8.The arms 2 are pivoted at their outer ends upon a fnlcrumwire 9 and workin radial slots 10 cut in a ring 11. Said arms 2 are connected by rods12 to key-levers 13 of the first order,` said levers being pivotedbetween their ends upon pins 11, projecting laterally from hangers orposts 15, which are rivetedat 16 upon the under side of a horizontalplate 17, which forms a portion of the base of the machine,springkeepers 18 being riveted at 19 tothe sides of said hangers toprevent accidental displacement of the levers from their fulcrum-pins,while enabling the detachment of any lever when desired. Each lever isprovided with a wire returning-spring 20 and a linger-key 21, the latterhaving a hollow stem 22, which works in a perforated guide-bar 23 and aguide-hole 24, formed in said plate 17. Said stem is connected to thelever by an attaching-piece 25, which is forked to bestride the forwardend of the key-lever, and is provided with a pin 26 to engage a shorthorizontal slot 27, formed in the forward end of the key-lever. The armsof the fork are made separable for permitting detachment of the lever,and the attaching-piece is formed with an upwardly-extending stem 28 forinsertion into the open lower portion of the tubular keystem 22. Y

The upper end of the connecting-rod 12 is pivoted at 29 to the type-bararm 2, and the lower end thereof is connected by an attaching-piece 25to the rear end of the key-lever, the latter being horizontally slottedat 30.

To the lower portion of. each rod 12 is pivoted at 31 the outer end ofone of a series of horizontal links 32, the inner disk-like ends 33whereof are arranged in an annular bear- IOO ing-groove of Ccross-section formed by centrally arranged upper and lower groovedplates 34 and 35, which are clamped together andv held upon a boss 36 bya screw 37, said boss being cast or xed upon the base-plate 17. Thelinks 32 are of equallength and radiate from the bearing-ring 34 indirections corresponding with the radial positions of their associatedtype-bars. The outer ends 31 of the forwardly and rearwardly extendingvlinks 32 at the middle of the machine lie almost directly over the rearends of the keylevers with which they are associated, theirconnecting-rods extending about vertically from the key-levers to thetype-arms, as illustrated at Fig. l. The width of the key-lever systembeing, however, greater than the diameter of the circle of vertical`connectingrods l2, the levers at the sides of the machine lie atincreasing distances outside of said circle. These outlying levers areconnected to the vertical rods 12 by means of lateral arms or offsets38, extending radially outward from the latter and varying in lengthaccording to the positions of their respective levers. At its outer endeach odset is formed with a down wardly-directed thimble or socket 39for receiving the stem of an attachingpiece 25, by which said offset isconnected to the key-lever. The upper end of the rod 12 is folded andbifurcated at 40 to straddle the type-bar arm 2, the tines of the forkbeing yielding, so as to enable the detachment of the rod from thetype-bar. The shouldered rivet 3l is provided with a large head toprevent undue sway of the links 32 and 12.`

When a key is depressed, its lever is vibrated upon the fulcrum 14 andthe rod 12 is thrust upwardly, thereby swinging the arm 2 and causingthe type to be impressed upon theplaten or the paper thereon. The keyshave substantially uniform dips, and the key-levers have substantiallyuniform movements at their rear ends, including those key-levers whichare arranged at the sides of the machine and connected to the offsets38. Since the rods 12 are pivoted upon the typebar arms 2 and the links32, all parts of said rods, including the offset arms 38, havesubstantially uniform vertical movements, and the outlying key-leversare equally effective with those at the center of the system inoperating the type-bars. It will be seen that if a link should beconnected to an extreme outlying key-lever and extended diagonallyupward to its type-bar without being guided at its lower endindependently of the key-lever there would occur at the operation of thekey a lateral thrust upon the key-lever which would cramp the same andimpede its movement; but by having the link l2 positively guided by aseparate device cramping action is avoided, and hence the key-levers maybe placed at any desired distance from the center of the machine, theoffsets 38 being correspondingly lengthened.

Upon the guiding-links 32 I arrange an antion thereof remaining at restand having a bearing upon the opposite link 32, whereby saiduniversalbar is enabled by acting as a lever of the second order to liftthe collar 45 and rod 44, which by a nut 46 thereon lifts the inner endof a forwardly-projecting arm 47, formed upon a dog-rocker 48, which ispivoted at 49 to a bracket 50. Said rocker is provided with areturning-spring 51 and carries at its upper end both a detent-dog 52and a feeding-dog 53, the latter being in engage ment with anescapement-wheel 54, which is connected by a pinion 55 and rack 56 toany suitable platen-carriage 57, propelled by a spring-barrel 58, towhich it is connected by a strap 59. Upon said movement of the dogrockerthe feeding-dog is disengaged from the escapement-wheel and thedetent-dog engaged therewith, and upon the subsequent return of thetype-bar and universal bar to normal position said dog-rocker vibratesin the reverse direction and permits an advance movement of the carriagein the usual manner. v

From the foregoing description it will be understood that the rods 12 atthe sides of the machine with their offset portions 38 constituteangular rods or links which are connected at their ends to the arms 2and to the levers 13 and thatthese rods comprise each horizontal andvertical arms.

Various changes may be made within the scope of the invention, someparts whereof may be used without others.
